Arithmetic of Functions problem Open ended

Answer 1

Answer: (gºh)(25)=2

Step-by-step explanation:

1. This exercise is about Composition of functions, then you have:

2. Then, you have that

(gºh)(25)$=g(h(x))=\sqrt{x}-3$

3. Now, you must substitute 25 into the function, as you can see below:

(gºh)(25)$=\sqrt{25}-3$

4. Simplify the fucntion.

5. Therfore, you obtain:

(gºh)(25)$=5-3=2$

Answer 2

Answer:

(g°h)(25) = 2

Step-by-step explanation:

We have given two functions.

Firstly, we have to find two composition of two functions and secondly, we have to find (g°h)(25).

g(x) = x-3 and h(x) = √x

(g°h)(x) = g(h(x))

Putting given values in above formula,we have

(g°h)(x) = g(√x)

(g°h)(x) = √x-3

Putting x = 25 in above equation, we get

(g°h)(25) = √25-3

(g°h)(25) = 5-3

(g°h)(25) = 2
